Educational Interventions for Cervical Cancer Screening Behavior of Women: A Systematic Review

Abstract

Background:

Cervical cancer is the second most common cancer in women worldwide; early detection can play a key role in reducing the associated morbidity. The objective of this study was to systematically assess the effects of educational interventions on cervical cancer screening (CCS) behavior of women.

Methods:

In this review the Cochrane library, Web of Science, Science Direct, PubMed, Scopus and search engine of Google scholar were searched for all interventional studies (trails, pre- and post-test or quasi-experimental) published in 2000-2017 for a systematic review, The search was based on the following keywords: cervix cancer, uterine cervical neoplasms, screening, prevention and control, Papanicolaou Test, pap test, pap smear, education, intervention, systematic review. Due to the heterogeneity of the data, a qualitative analysis was performed.

Results:

Thirty seven articles with 15,658 female participants in different parts of world were included in the review. About three quarters of the articles covered behavior change interventions. About one fourth of the articles were based on health education methods. The heath belief model is the most popular used framework for cervical cancer screening interventions. The results of our study showed that different health education methods (such as calls, mailed postcards, mother/daughter education. consultation sessions, picture books, videos, PowerPoint slides, small group discussions, educational brochures, radio broadcast education, lecture presentations, tailored counseling and a fact sheet, Self-learning package, face-to- face interviews and etc) are effective in modifying cervical cancer screening behavior of women.

Conclusions:

Our results showed that the different interventions and health behavior change frameworks provide an effective base for cervical cancer prevention. Heath providers can chose educational methods based on the particular client situations.

Introduction

Cervical Cancer is one of the most common malignancies in women (Nwankwo et al., 2011). It is estimated that in all over the worldwide about 1.4 million women are living with Cervical cancer (second most after the breast cancer), the cervical cancer is the second most common cancer in women worldwide, also it is the leading cause of cancer death in some developing countries (Organization, 2015).

Screening can reduce both the mortality and incidence of cervical cancer (Mishra et al., 2011). The World Health Organization knows cervical cancer as a preventable disease in women (Bleggi et al., 2003). The treatment of cervical cancer is less effective because the sign and symptom of this cancer does not appear until the advance stages. The cause of cervical cancer is the Human Papilloma Virus (HPV) (Group, 1995). The epidemiologic risk factors of this cancer are onset of coitus in young ages, history of sexually transmitted disease, larger number of sexual partners, use of contraceptive methods, history of smoking, parity and chronic immunosuppression (Partridge et al., 2014). Now in the developed countries CCS is carried out by cytological examination of a the Pap test (Hanaa, 2014; Koliopoulos et al., 2010). Women’s decisions regarding CCS are affected by many factors including: sociocultural factors (Johnsonet al., 2008), cancer awareness (Austoker et al., 2009), knowledge (Nwankwo et al., 2011), attitudes (Reis et al., 2012) and women’s beliefs (Esin et al., 2011), lack of encouragement (Fernández-Esquer and Cardenas-Turanzas, 2004), providers’ attitudes (McFarland, 2003), recommendation from health professionals (Chan et al., 2016) and etc.

The world health education mentioned that “Health education is an exchange of information with the purpose of increasing awareness and knowledge about how to keep healthy and prevent diseases (such as cervical cancer), including information about resources that are available and the benefits of accessing services” (Health, Diseases, and Promotion, 2006). Evidence showed that Education by raising awareness, improving accessibility to services, increasing individuals’ efficacy and empowering over future choices can enhance the demand for preventative health services (Sabates and Feinstein, 2006).

Systematic reviews aimed to generate new knowledge and provide a rigorously reviewed summary of relevant literature on a specific question and synthesize the results of these literature (Wallace et al., 2014), because of the importance of the CCS, and lack of overall articles on effectiveness of educational interventions in this issue, this study was carried out to systematically assess the effect of Educational Interventions to improve cervical cancer screening (CCS) behavior of women.

Materials and Methods

Search Strategy

This study is a systematic review conducted to determine the effect of educational interventions on CCS behavior of women, in this study we assess all published articles (Trails, pre- and post-test design or quasi-experimental) from July 2000 to May 2017 in English language. We searched from Cochrane library, Web of Science, Science Direct, PubMed, Scopus and search engine of Google scholar. The search was based on the following search terms: cervix cancer, Uterine Cervical Neoplasms, screening, prevention and control, Papanicolaou test, Pap test, Pap smear, education, intervention, systematic review.

Criteria for considering studies for this review Selection of studies

Two authors reviewed the eligibility of interventional design studies and also evaluated the risk of bias and the data for included articles such as information on the study population, country of origin, the number of participants in each group, study design, aim, measurement tools, the type of educational intervention, and adverse effect of each intervention and main results of study was extracted.

Types of Participants

All educational intervention studies (Trails, pre- and post-test or quasi-experimental) with inclusion criteria of women without a previous cervix cancer diagnosis.

Types of Interventions

All intervention studies (Trails, pre and post-test or quasi-experimental) involving educational intervention versus usual care or versus without educational intervention.

Types of Comparator/control

No intervention or usual care.

Types of Outcome measures

Educational interventions based on different health models adverse outcomes related to false positive findings of symptoms (such as decreased quality of life/increased anxiety and any of the adverse outcomes) assessed by any validated scale.

Risk of Bias

The EPHPP is a generic tool used to evaluate a variety of intervention study designs. This tool assesses six domains: selection bias, study design, confounders, blinding, data collection method and withdrawals/dropouts. According Guidelines for this tool each domain is rated as weak (1 point), moderate (2 points) and strong (3 points) and domain scores are averaged to provide the total score. The maximum total score per study is 3.00. Based on their total score, quality of studies is rated as weak (1.00–1.50), moderate (1.51–2.50) or strong (2.51–3.00) (Armijo-Olivo et al., 2012; Deeks et al., 2003; Thomas et al., 2004). Search in databases was performed by two researchers; the abstracts were first assessed and then some articles underwent final assessment according to EPHPP and inclusion criteria (including published from 2000 through May 2017 included an intervention based) and Exclusion criteria (Full-text not accessible, Studies not demonstrating a clear research methodology).

Data analysis

In this review due to the heterogeneity of the data, qualitative analysis was used.

Results

In this review study thirty seven articles with 15658 female participants included. 38.8 % of studies were from Asia, 13.8% from Europe, 33.3% from Americas and 13.8% from Africa. Table 1 showed the Characteristics of included studies.

Behavior change based interventions Health belief model (HBM)

Kocaöz et al., (2017) and Champion et al., (2006) in their study reported that professional education program have positive effect on pap test behavior of women. Shobeiri and Roshanaei, (2016) reported that HBM-based education had a key role on changing women’s beliefs about CCS. Taghi Pour shoorijeh et al, (2015) reported that HBM based intervention can enhance the awareness and uptake of pap test. Daryani et al., (2015) showed that education based on HBM was effective in enhancing women’s performance about CCS. Guvenc and Yenen, (2013) reported that three-stage nursing intervention could help to increase participation of Turkish women in Pap testing. Bebis et al., (2012) reported that HBM educational based model significantly increased the knowledge, perceived susceptibility cervical cancer and barriers of pap testing. Pirzadeh and Mazaheri, (2012) reported that HBM based educational intervention promote CCS behavior of women. Shojaeizadeh et al., (2011) concluded that HBM based health education can enhance women’s knowledge and health beliefs and CCS behaviors. In Karimy et al., (2011) study theories and models of changing of individuals’ behavior is effective programs on CCS. The results of Park and Chung, (2005) study showed that cognition-emotion focused program have a role on women’s decisions to have Pap smear. The results Jibaja-Weiss et al., (2003) showed that one year after the intervention that personalized form-letter group was significantly more likely to have undergone a Pap testing.

Social cognitive theory (SCT)

Peterson et al., (2010) reported that among mobility impairments women PATHS intervention enhanced the pap testing. Nuno et al., (2011) reported that a promotora-based education enhace the CCS behavior of Hispanic women.

Trans Theoretical Model (TTM)

In Krok-Schoen et al., (2016) study showed during the intervention 63% of the Ohio Appalachian women had forward stage movement. Hou et al., (2005) reported that at the end of the program women in the intervention group were 2.31 more likely and in contemplation stage 4.18 were more likely to receive a CCS. In Abdullah and Su, (2013) study results showed that in both groups, pre-contemplation stage was had the highest proportion of changes in all stages.

Precede-Proceed Model

Katz et al., (2007) reported that implementation of ROSE project (which was designed to improve breast cancer screening in Carolina) significantly increased The rate of CCS in both group of participants.

Protection Motivation Theory (PMT)

In the Dehdari et al., (2014) study the results showed that in the intervention group the mean scores of self-efficacy and intention variables were significantly higher than CON (p<0.05); But the result showed that there were No significant differences in the perceived severity, response cost, response efficacy, and fear. In the intervention group higher percent of women had obtained first and second Pap smear compared to the CON. The result of Ghahremani et al., (2015) study showed that educational based on PMT is effective in pap testing among participants. PMT was introduced by Rogers as a predictive theoretical model of health behaviors. This theory proposes that two appraisal processes, i.e. threat and coping appraisal, occur when the individual receives threatening information. Threat appraisal is associated with a maladaptive response. It involves the perceived severity of a threatening event and personal vulnerability to the proposed threat (Dehdari et al., 2014).

Combined model

Maxwell et al., (2003) reported that small group community-based education base on Health Belief Model, the Theory of Reasoned Action/Planned Behavior and the Precede Model only effective in increasing CCS among participants who had very low baseline CCS rates. Coronado et al., (2016) reported that the knowledge and intention to CCS of participants based on HBM/TTM theory education intervention significantly increased.

Health education methods

In Gana et al., (2016) educational program increased cervical cancer and Pap test awareness however, even after intervention the uptake of Pap testing remained low. In Thompson et al., (2016) study results showed that in-home, promotora-led educational intervention improving CCS. in Patricia et al., (2016) study the awareness and intention of mothers were changed after their daughter education (Obulaney et al., 2016). Rosser et al., (2015) reported that the educational intervention could help to increase knowledge and awareness about CCS, however it did not result in higher CCS rates. Hanaa et al., (2014) reported that after self-learning educational package the perceive and knowledge of intervention group increased and the 53.5% of the intervention group compared with 5.7% of the CON intent to do pap test. The result Abiodun et al., (2014) showed that health education had significant effect on the awareness of CCS (p < 0.0001). Also in the intervention group the mean score of knowledge, perception and uptake of cervical screening were improved. Lai et al., (2014) and Gahremani-nasab et al., (2014) reported that School-based education had positive effect on cervical cancer prevention. Choi, (2013) and Moodi et al., (2011) in their study reported that education program with picture book, lecture and discussion significantly improved the knowledge and CCS of Korean women. Marek et al., (2012) reported that, school-based, educational intervention effective in improving knowledge, beliefs and attitudes. Love and Tanjasiri, (2012) reported that entertainment-education video and brochure could help to increasing knowledge and attitudes. In O’Brien et al., (2010) study promotora-led intervention significantly improved pap test using rate also could help to increase self-efficacy and cervical cancer knowledge of women. Wright et al., (2010) reported that Community Education improved the cervical cancer awareness of women. Choe et al., (2009) and Guvenc et al., (2011) reported that education by video in deaf women improved the cervical cancer knowledge. Perkins et al., (2007) reported that community-based educational intervention with lecture presentations and radio broadcasts increase CCS behavior of women. Holloway et al., (2003) and Moodi et al., (2011) reported that the intervention had a substantial benefit for CCS. In Taylor et al., (2002) study 39% of women in outreach group, 25% in the direct mail group and 15% in the CON reported Pap testing in the interval between randomization and follow-up data collection.

Discussion

Cervical cancer is a common women cancer our study systematically assess the effect of Educational Interventions to improve cervical cancer screening (CCS) behavior of women. The result of our study showed that educational interventions based on health behavior change theories could help to improve CCS behavior of women in different part of the world. Theories of health behavior change indicates that increasing self-regulation skills and developing knowledge and beliefs lead to the change of health behavior (Ryan, 2009). The result of a review showed that behavioral interventions example mailed or telephone reminders increased pap test usage by 18.8% (Yabroff et al., 2003). Roncancio et al, (2013) reported that Theory of Planned Behavior Model is a useful model for understanding CCS intentions. Coronado et al., (2015) reported that theory-based education intervention lead to increasing knowledge and promoting awareness and increasing screening rates.

The result of our study showed that different health education methods (such as calls, mailed postcards, mother/daughter education, consultation sessions, video, PowerPoint slide, small group discussion, educational brochure, radio broadcasts education, lecture presentations, tailored counseling and a fact sheet, Self -learning package, face-to- face interviews and …) are effective in CCS behavior of women. The evidence show that an educational intervention can help to reduce barriers of CCS and subsequently can help to increase CCS rate (Coronado et al., 2015). Soares and Silva, (2016) in their review about interventions that facilitate adherence to Pap smear exam reported that use of case manager; media outreach work; telephone call; invitation letter increase women’s knowledge about CCS. Lu et al., (2012) in their systematic review about interventions to increase breast and cervical cancer screening uptake in Asian women reported that the combination workplace-based group education programs with mobile screening services and attending screening are effective in promotion breast and cervical cancer screening uptake. Roy et al., (2008) in the systematic review reported that use of client reminders, one-on-one education and small media improve cervical cancer screening behavior of women (Baron et al., 2008). Sabatino et al., (2012) in their systematic review reported that client reminders and one-on-one education and reducing structural barriers improve the CCS behavior (Spadea et al., 2010). In another systematic review reported that community demand for screening increased with education by: Mass media, Client reminders and recall, Client incentives, Laws to increase screening, Reducing structural barriers, Reducing client out-of-pocket costs, Provider assessment and feedback (Baron et al., 2008). Evidence show that organized screening programs can improve the cervical cancer screening (Spadea et al., 2010).

Limitation

Our study did not include the ‘grey’ literature so Future research need to survey this literature.

In conclusion, different interventional and health behavior change framework models are effective method in cervical cancer prevention. Heath providers can chose educational method based on the client situations.
